Bug #: 50325 Summary: Glyphy bad render on r600g (software render is fine) Classification: Unclassified Product: Mesa Version: 8.0 Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: edwin+mesa@etorok.net
Created attachment 62078 --> https://bugs.freedesktop.org/attachment.cgi?id=62078 apitrace (cf. https://github.com/apitrace/apitrace/tree/1.0)
I just tried Glyphy on r600g and the output is very bad. Don't know if its Glyphy bug or Mesa bug, but if I force software rendering in Mesa then I do see the output.
Attached screenshots of bad (r600g) and good (software render).
The bad render was obtained by: demo/glyphy-demo
The good one: LIBGL_ALWAYS_SOFTWARE=1 demo/glyphy-demo
I tested on: OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD RV730 OpenGL version string: 2.1 Mesa 8.0.2 OpenGL shading language version string: 1.20
I'll try to test on mesa git later to see if its still an issue there.
Also attached is a an apitrace, and the bad render can be reproduced with: build/glretrace lt-glyphy-demo.trace
The good render (initialization a bit slow, but works): LIBGL_ALWAYS_SOFTWARE=1 build/glretrace lt-glyphy-demo.trace
